SPECIFICATION forming part of Letters Patent No. 546,006, datedSeptember 10, 1895.

Application tiled November l5, 1894. Serial No. 523,846. (No modeld ToaZZ whom it may concern;

Be it known that I, JOHN F.. DOLBER, a citizen of the United States,residing at Manchester, in the county or" Hillsborough and State of NewHampshire, have invented certain new and useful Improvements inShuttle-Threaders; and I do declare the following to be a full, clear,and exact description ofthe invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the letters ofreference marked thereon, which form a part of this specitication. i

i This invention relates to improvements in threaders for loom-shuttles,and has for its object the production of asimple and eflicient threaderpossessing advantages in point of precision in operation and durability.

vThe nature of my invention will appear from a reading of the followingdescription, when taken in connection with the accompanying drawings,which form a part of this specilication, and in which- Figure lis aperspective view of a loomshuttle. Fig. 2 is an elevation of my improvedthreader. Fig. 3 is a similar view, but showing a modified form. Fig. 4isa detail View of 'the removable brush portion, and Fig. 5 is a detailview of one of the arrangements for holding the removable brush portion.

Referring to the said drawings by letter, A denotes the shuttle which isprovided with the usual pot-eye b and the side eye c, and d is thethread, which in practice is deposited in the pot-eye and is drawnthrough the side eye by the use of my improved threader. The threadercomprises a handle e, in one end of which is inserted and held the shankf for the brush, and secured to and projecting laterally from said shankis a finger g, having a recessed or notched end g', which in practiceengages the thread and forces it to the bottom of the pot-eye.

The brush portion h (shown in detail in Fig. 4;) :is cylindrical in formand consists of bristles spirally arranged on a shank h', formed oftwisted wire, and this brush portion is adapted to be secured to theholder in a manner to permit its ready removal when worn and thesubstituting of a new brush.

I have shown in the drawings two arrangeto be turned in the shank f inthe manner shown in Fig. 2. The brush portion being cylindrical in shapemay be turned or screwed into the coil, the flexible bristles readilyfollowing the spiral turns, and when the brush is so inserted thebristles project beyond the coil sufficiently to engage the thread whenthe threader is inserted and partially rotated in the side eye.

Fig. 2 shows the threader when ready for operation, the brush portionbeing arranged within the coil and interposed between the closed end t"and the end of the shank f. Vhen the brush from constant use becomesworn and useless, the coil is turned until disconnected from the shankf,the brush is withdrawn by rotating it in the reverse direction and a newbrush is inserted.

Referring now to Fig. 3, the shank fis divided into four parts, each ofwhich terminates in a jaw j, and these four jaws receive and hold thebrush when the jaws are closed by a sleeve or ring Zc,which latter isslidable on the shank. The bristles of the brush project beyond thejaws, as shown, and when worn and useless the brush is removed and a newone inserted by sliding the ring downward and opening said jaws, as willbe understood.

In practice, the thread being deposited by the linger in the base ot'the pot-eye, the brush is inserted to the depth ot' the side eye, andupon being slightly rotated the bristles engage and hold the thread, andas the brush is withdrawn the thread is drawn through the eye and theoperation is completed.

The arrangements for securing the brush to the holder, aside fromproviding for the ready and rapid substitution of new for worn anduseless brushes prolong the'life of each brush by the protection whichthey afford, inasmuch as both the coil and the jaws are of a size tonearly fill the side eye, and consequently the liability of wear on'thebrushes is reduced.

I claim as my inventionl. A shuttle threader comprising a holder and ashank secured thereto, said shank having an open-work receptacle at itsfree end, and a removable brush portion held within said open-Work andextending through and beyond the same, whereby said brush is adapted tobe brought into frictional scraping Contact with the end and side Wallsof the side eye of the shuttle and to engage and Withdraw the threadtherefrom, substantially as described. 2. A shuttle threader comprisinga holder and a shank secured thereto, said shank being provided with areceptacle having a plurality of interstices, and a removable brushportion held Within said receptacle, and having the bristles extendingthrough and beyond said interstices for the purpose set forth.

3. In combination With a holder, a brush and a spiral coil adapted toreceive said brush and removably secured to said holder.

4. A shuttle threader comprising a handle, a shank, a brush cylindricalin shape, and a spiral coil adapted to receive said brush and removablysecured to said shank.

In testimony whereof I afx my signature in presence of two witnesses.

JOHN E. DOLBER.
